ANCHOR-ING DEVICE.

Application filed October 28, 1921.

To all whom t may concern.' w

Be it known that I, HOWARD C. lVlAHoN,

a citizen of the United States, residing at East Liverpool, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in finchoring Devices, of which the following is a specification.

rthis invention relates to new and useful improvements in anchoring devices.

The primary object of my invention is to provide a device of the above character for anchoring wooden floors to concrete floors or anchoring machinery or appliances of any kind to floors, walls and ceilings of new building and more especially concrete buildings.

With the foregoing and other objects in view that will appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts illustrated in the drawings and more particularly pointed out in the appended claims.

ln the accompanying drawings, which are for illustrative purposes only and are therefore not drawn to scale Fig. 1 is a view, partly in side elevation and partly in section, illustrating the application of my invention.

Fig. 2 is a side elevation of the anchoring device.

Fig. 3 is a central longitudinal section of the anchoring device, with the corresponding sleeper and a portion of the wooden floor, also shown in section.

Fig. 4: is a top plan view of the anchoring device.

Fig. 5 is a horizontal section, taken on line 5-5 of Fig. 3.

Fig. 6 is a bottom plan view.

Fig. 7 is a view partly in side elevation and partly in section, illustrating more particularly the use of an attachment in some cases.

Fig. S is a detail perspective view of the attachment and Fig. 9 is a similar view of the metal washer plate.

Referrin to the drawings for a more particular description of the invention, and in which drawings like parts are designated by like reference characters throughout the several views, my improved anchoring device essentially comprises two telescopic inner and outer members 1 and 2, respectively. -Section or member 1 consists of the Serial No. 511,051.

base 3 and body portion 4 of rectangular oblong form in cross-section, formed throughout its length with a central longitudinal slot 5 adapted to receivethe head 6 of the T-bolt' 7. ln practice, the side walls 8 of the inner section 1 are cut away at their lower edges, as at 9, in such a manner as to leave the oppositely disposed recesses 10 and the diagonally disposed inwardly eX- tending lugs 11. ln use, the head 6 of the T-bolt is inserted in the slot 5 from the top, when by giving it a quarter-turn, it may be raised to engage and seat in the recesses i( and will be prevented from turning in tightening or loosening the bolts.

.The outer section 2 nts over the inner section 1, as shown in Figs. 1 and 3, with its open bottom edge bearing on the base flange 12 and its top 13 fitting over the top of the inner'section.l rihe top wall 13 of the outer section is provided with an elongated slot' 141 which registers with the slot 5 of the inner section and the side and end walls 15 and 16 of the outer section with the cutwardly projecting` longitudinal and transverse flanges or wings 17' and 18, respectively, which are embedded within the concrete floor.

The inner section 1 is fastened by the bolts 19 or other equivalent means to the metal plates or beams 2O and the concrete is poured preferably flush with the top of the outer section 2,'as shown in Figs. 1 and 3. A flat rectangular washer piate 21 :lits on top of the outer section and is provided with a central transverse aperture 211 to receive the shank of the T-bolt. A coating 22 of red lead paint is applied between the top of the outer section and the washer plate to form an air tight joint or connection. The upper ends of the T-bolts entend through and are fastened to the sleepers 23 on which the wooden -floor 2dis laid in the usual manner. l idhen the anchor device is already in place and it is desired to add another layer of concrete, or when it is desired to anchor the device ata greater depth at the outset, than is usually the case, the attachment 25, shown more particularly in Figs. 7 and 8, is em ployed. This attachment is of rectangular oblong form in cross section, is fastened to the top of the outer section 2 by screws 26 or other equivalent means and serves as a reduced extension therefor. The attachment is provided throughout its length with a slot 27 to receive the shank 28 of the T-bolt walls are provided at their inner lends with recesses, an outer section fitting over the inner section and provided in its outer Wall with a slot registering With that of the inner section and a nibolt arranged With its head engaging the recesses ofthe inner section and its shank extending through and above the slots of the inner and outer sections.

2. An anchorii'ig device of vthe character speci'lied, comprising a pair of 4inner and onter telescopic sectioiisprovided with regis tering slots, a wlbolt'arranged With its head 'l removably engaged with the slotted portion or' `the inner section and its shanlr extending 'I v through yand beyond the slotted portions of the two sections, anda Washer plate fitting on the slotted outer Vivall of the outer' section and having a transverse aperture to receive the shank of the bolt.

'3. An anchoring device of the character specified, comprising a pair of inner andv outer telescopic sections provided With registering slots, boltarranged withy its head removably engaging the inner section yand its shank extending through and beyond the two sections, a .Washer plate iitting` on the outer Wall of the outerl section and a liquid coating applied between said outer Wallv and said Washer plate.

li. An anchoring device of the character specified, comprising an inner section formed With a longitudinal slot, an outer section fitting over the inner section and providedin kits outer Wall with a slot which registers with that of the latter, said outer section being arranged with itsl outer Wall Hush with the outer surface of the jfloonwall or ceiling of the building, a lm-bolt arranged With its head removably engaged with the inner sec-` tion and its shank extending through Vand beyond the slotted portions of the two sections and a metal Washerl plate tting over the outer Wall of the outer section, said plate,

provided with a transverse aperture to rey ceive the shank of the bolt. y

5. An anchoring device of the character specied, comprising a `base consisting of a pair of inner andouter telescopic sections, a

third section-secured tothe outerpwall of,v

the outer sectionand forming a neck or re-v duced extension therefor, a flange at the outer endv of vsaid third section, a Washer plate` litting over said flange and a bolt removably engaged With the inner end of the inner section f ot thel base and extending through both the inner and outer sections of the'base andthrough and beyond` the third extension forming section and the Washer plate. v f,

In testimony whereof I atliX my signature.
